Abstract

PROBLEM TO BE SOLVED: To provide a standing body monitoring system capable of positively identifying that a person has climbed for no transmission of wasteful warning.SOLUTION: A plurality of non-contact temperature sensors 12 each detecting heat of an object and outputting a detection signal are arranged at regular intervals along the standing direction of a steel tower 2 toward a substantially horizontal direction. The plurality of non-contact temperature sensors, when a detection signal is output in order from the downstream side within a predetermined time, determines it to be under a human climbing state on the steel tower rather than a missile or sunshine and transmits an alarm signal.

Description

  The present invention relates to a standing body monitoring apparatus that detects that a person has climbed a standing body such as a transmission line tower and transmits an alarm signal to a related person.

  In order to prevent people from climbing to the transmission line tower, conventionally, a fence was installed around the tower installation location to prevent people from entering the tower site, and it was attached to the main pillar of the tower. Although measures are generally taken to prevent climbing towers with shields, in the case of steel towers that are not sufficiently monitored by humans, there is a disadvantage in that it is impossible to detect when an outsider climbs the steel tower. ing.

  In order to avoid such inconvenience, for example, an electromagnetic shield container is attached to a high voltage danger point such as a transmission line tower, and a sensor is provided in the container to detect when an electrician approaches, and an alarm sound is generated when the sensor is activated. An alarm device for power transmission line towers is considered.

However, the configuration described above only determines whether or not a person has approached the steel tower, and cannot reliably determine whether or not a person is climbing. In addition, the above-described configuration reacts not only to people but also to birds and flying objects, so that birds and flying objects cannot be distinguished from humans, and there is a disadvantage that many unnecessary alarms are generated. For this reason, every time there was an alarm, it was necessary to go to the site and confirm it, which was unbearable.
The present invention has been made in view of such circumstances, and it is a main problem to provide a monitoring apparatus for a standing body that can reliably specify that a person has climbed and does not issue an unnecessary alarm. Yes.

  In order to achieve the above object, a standing body monitoring apparatus according to the present invention has a plurality of non-contact temperature sensors that sense the heat of an object and output a detection signal with the plurality of non-contact temperature sensors directed substantially horizontally. It is installed at intervals along the standing direction, and when the plurality of non-contact type temperature sensors sequentially output detection signals from the bottom within a predetermined time, it indicates that the person is up to the standing body It is characterized by comprising determination means for determining, and transmission means for transmitting an alarm signal when it is determined by the determination means that the person is in an uphill state.

Therefore, when a person begins to climb the standing body, detection signals are sequentially output from the lower non-contact temperature sensors among the plurality of non-contact temperature sensors arranged on the standing body. Is determined to be in the upstream state, and an alarm signal is transmitted by the transmission means.
Here, two or more non-contact temperature sensors may be used to determine that a person has climbed, but in order to more reliably specify that a person has climbed, three or more non-contact type temperature sensors are required. It is desirable to provide the temperature sensor along the standing direction of the standing body.

  Further, the present invention may be applied to a standing body such as a utility pole or a building. However, when assuming a steel tower provided with a plurality of main pillar materials as the standing body, the plurality of non-contacts The mold temperature sensor may be arranged on a substantially center line of the standing surface including the adjacent main pillar material, and the detection direction may be set toward the main pillar.

  Further, the determination means determines that the reaction is caused by the heat of sunlight when all the non-contact temperature sensors output detection signals simultaneously, and when only one of the non-contact temperature sensors outputs a detection signal. It is further provided with a function for determining that a bird or a flying object has passed, and when the transmission means determines that the reaction is due to the heat of sunlight by the determination means, and when it is determined that a bird or a flying object has passed, the determination You may make it further provide the function to transmit a result.

  As described above, according to the standing body monitoring device of the present invention, a plurality of non-contact temperature sensors are arranged in the horizontal direction at intervals along the standing direction of the standing body. When the non-contact type temperature sensor outputs a detection signal sequentially from the bottom within a predetermined time, it is determined that the person is in an ascending state to the standing body, and an alarm signal is transmitted. It is possible to distinguish from a case where a non-contact type temperature sensor reacts when a bird or a bird passes, and it is possible to reliably specify that a person has climbed and to avoid issuing an unnecessary alarm.

The top view of the part in which the sensor explaining the positional relationship with a contact-type temperature sensor was provided, (c) is explanatory drawing which shows the structure of a detection part. FIG. 2 is a diagram illustrating an installation state of the non-contact type temperature sensor attached to the steel tower. FIG. 3 is a flowchart illustrating an example of a control operation by the detection unit.

  Hereinafter, the standing body monitoring device of the present invention will be described with reference to the accompanying drawings when applied to a transmission line tower as a standing body.

  1 and 2 show an example of a transmission line tower 2 to which the standing body monitoring device 1 is attached. The transmission line tower 2 is known per se, and is composed of four main pillar members 4 whose lower ends are supported by a base body 3 embedded in each apex part of a substantially square shape in plan view of the ground, and a main pillar A plurality of horizontal members 5 which are spaced between the main pillar members 4 and spaced apart in the standing direction of the members 4, and a plurality of diagonal members 6 which are spanned between the horizontal members 5. Configured. As the steel material constituting the transmission line tower 2, generally equilateral mountain-shaped steel or hollow steel pipe is used. In this example, a steel pipe tower in which the main pillar material 4 is constituted by a hollow steel pipe is used.

The horizontal member 5 is composed of a single member extending in the horizontal direction, the intermediate portion thereof is fixed to the intermediate plate 7 by welding or the like, and both end portions are fixed to the gusset plate 8 fixed to the main column member 4. It is connected by bolts and nuts.
Further, the diagonal member 6 is connected to a gusset plate 9 having one end fixed to the main column member 4 and to the intermediate plate 7 at the other end by a plurality of bolts and nuts.

  In such a steel tower, a standing body monitoring device 1 for detecting a state in which a person is climbing up to the steel tower is grounded at a portion below the intermediate position in the height direction of the steel tower. The standing body monitoring apparatus 1 fixes a sensor mounting bracket 11 between upper and lower intermediate plates 7 with bolts or the like along a standing direction of a steel tower, and senses the heat of an object on the sensor mounting bracket 11. A plurality of non-contact temperature sensors 12 that output detection signals are arranged at intervals along the standing direction of the tower 2, and the detection signals of each sensor are fixed to the tower 2 in the vicinity of the sensor mounting bracket 11. The detection unit 13 is aggregated.

  In this example, the sensor mounting bracket 11 is fixed so that both side surfaces thereof face the main pillar member 4 disposed on both sides of the sensor mounting bracket 11, and the non-contact type temperature sensor 12 is the sensor mounting bracket 11. The non-contact type temperature sensor fixed to each side surface at three equal intervals and attached to one side is the same as the non-contact type temperature sensor attached to the other side in opposite directions. It is provided at the height position. Each of the non-contact sensors 12 has directivity, and is installed with the detection direction directed in the horizontal direction and with the main pillar material 4 adjacent thereto.

  Therefore, the non-contact type temperature sensor 12 is arranged on the substantial center line of the virtual upright surface including the adjacent main column members 4 toward the main columns on both sides, and has four upright surfaces. In the embodiment, a total of 24 are provided.

  In addition, in order to specify the non-contact type temperature sensor installed on each surface of the steel tower, as shown in FIG. 1 (b), the main column material I and the main column material I, II, III, and IV On the virtual upright surface including the main pillar material II, three non-contact temperature sensors 12 directed to the main pillar material I are arranged as A-row sensors (A-1, A-2, A-3 from the bottom), the main The three non-contact type temperature sensors 12 directed to the pillar material II are B-row sensors (B-1, B-2, B-3 from the bottom), and a virtual stand including the main pillar material II and the main pillar material III. In the installation surface, three non-contact type temperature sensors 12 directed to the main pillar material II are arranged in a C row sensor (C-1, C-2, C-3 from the bottom), and three The non-contact type temperature sensor 12 is a D-row sensor (D-1, D-2, D-3 from the bottom), and in the virtual standing surface including the main column member III and the main column member IV, the main column member III Three non-contact types aimed The degree sensor 12 is an E-row sensor (E-1, E-2, E-3 from the bottom), and the three non-contact type temperature sensors 12 directed to the main pillar material IV are F-row sensors (F-1, F-2, F-3), and three non-contact temperature sensors 12 directed to the main pillar material IV on the virtual upright surface including the main pillar material IV and the main pillar material I are G-row sensors (lower To G-1, G-2, G-3), and three non-contact type temperature sensors 12 directed to the main column I are H-row sensors (from the bottom H-1, H-2, H-3). To do.

  The detection unit 13 may be provided for each column sensor, or only one detection unit 13 may be provided for all sensors attached to the steel tower. In this example, the detection signals of all the sensors are detected. A single detection unit 13 is integrated. The detection unit 13 is based on a detection calculator 21 that inputs a signal (detection signal) from each non-contact type temperature sensor 12 of each column sensor, and the input signal from each non-contact type temperature sensor 12. When it is determined that a person is climbing, an alarm signal is transmitted, and when it is determined that it has reacted to solar heat or when it is determined that birds or flying objects have passed, the determination result is transmitted. The transmitter 22 is configured to include a power source 23 that supplies power to the detection computer 21 and the transmitter 33.

  The transmission unit 22 has a function of transmitting an alarm signal and a determination result via the Internet, a telephone network, and the like. For example, the transmission unit 22 is configured by a mobile phone or the like arranged in the casing of the detection unit 13, and this transmission The alarm signal and the determination result transmitted from the unit 22 are transmitted to the terminal 25, the mobile phone 26, and the like installed at the control center and the facility main place 24.

  In addition, the power supply 23 is comprised by the storage battery etc. which were charged with the solar cell, and can supply the stable electric power even when the electric power generation by a solar cell is not enough. In addition, when the terminal 25 or the mobile phone 26 installed in the control center and the facility management place 24 receives an alarm signal or a determination result sent from the transmission unit 22, the terminal 25 or the mobile phone 26 emits an alarm sound or alarm information or a determination result. Is displayed on the screen.

  Next, an example of the operation process in the detection computer 21 in the above configuration will be described based on the flowchart shown in FIG. The processing example according to this flowchart is performed independently for each column sensor (A-row sensor to H-row sensor), and the sensor 1 is a non-contact type temperature sensor (A-1 to H) in the lower stage of each row sensor. -1), the sensor 2 indicates a middle non-contact temperature sensor (A-2 to H-2), and the sensor 3 indicates an upper non-contact temperature sensor (A-3 to H-3).

  First, the detection computer 21 inputs sensor signals from the upper, middle, and lower non-contact temperature sensors (sensor 1, sensor 2, sensor 3), and monitors whether or not an object that generates heat is detected. (Step 50).

  In step 52, it is determined whether or not the three non-contact temperature sensors (sensor 1, sensor 2 and sensor 3) in the upper, middle and lower stages have reacted at the same time and output detection signals, and have reacted at the same time. If it is determined, it is determined that the reaction is due to the heat of the sun (step 54), and the determination result is transmitted to the terminal at the control center and the facility main location or the mobile phone via the transmitter (step 56). In response to this, the terminal 25 or the mobile phone 26 at the control center and the facility management point 24 displays the determination result on the screen.

  If it is determined that the three non-contact temperature sensors (sensor 1, sensor 2, sensor 3) are not reacting at the same time, then either one of sensor 1, sensor 2, or sensor 3 has reacted. (Steps 58, 60, 62).

  Among these, if it is determined in step 58 that the sensor 1 has reacted, the process proceeds to step 64 to determine whether the sensor 2 has reacted before the predetermined time has elapsed after the sensor 1 has reacted. If it is determined in step 64 that the sensor 2 has reacted, the process proceeds to step 66 to determine whether the sensor 3 has reacted before the predetermined time has elapsed after the sensor 2 has reacted.

  When the sensor 1 reacts and then the sensor 2 reacts before the predetermined time elapses and then it is determined that the sensor 3 reacts before the predetermined time elapses, the heating elements sequentially move from the bottom of the tower 2. Since the state has been detected, it is determined that the person is climbing the tower (step 68), and the alarm signal is sent to the terminal 25 of the control center and the facility main point 24 via the transmitter 22 or The data is transmitted to the mobile phone 26 (step 70). In response to this, the terminal 25 or the mobile phone 26 at the control center and the facility management site 24 emits an alarm sound or displays alarm information on the screen.

On the other hand, if the sensor 1 has reacted, but the sensor 2 has not reacted before the predetermined time has elapsed (only the sensor 1 has reacted), or if only the sensor 2 has reacted in step 60, When only the sensor 3 reacts in step 62, it is determined that birds or flying objects have passed (step 72), and the determination result is transmitted to the terminal 25 of the control center and the facility main place 24 via the transmission unit 22 or the mobile It transmits to the telephone 26 (step 74). In response to this, the terminal 25 or the mobile phone 26 at the control center and the facility management point 24 displays the determination result on the screen.
Thereafter, after the predetermined time has elapsed, the determination result is reset, and the processing after step 50 is repeated (step 76).

  Therefore, according to the above configuration, when a person ascends the steel tower, the main pillar material 4 is often ascended from the bottom in order, so that in order of sensor 1 → sensor 2 → sensor 3 in order. By capturing the reaction (sequentially outputting detection signals), it is possible to recognize that a person has climbed the tower, and it is possible to distinguish it from the reaction caused by solar heat and the passage of flying objects or birds. Become. For this reason, it is possible to improve the monitoring accuracy, and it is possible to eliminate unnecessary alarms due to passage of solar heat, birds, or the like.

  Moreover, since the non-contact type temperature sensor 12 is attached to each standing surface of the tower 2, by performing the above-described processing on the sensors in each row, the rise of the person regardless of where the tower 2 rises. It is possible to detect the state, and it is also possible to determine which part of the tower is rising by separately managing the output of the sensors in each row. That is, when the rising column of the person is determined by the A-row sensor and the H-row sensor, it can be determined that the main column material I is rising, and when the rising column of the person is determined by the B-row sensor and the C-row sensor. If it is determined that the main column material II is ascending, and the column D sensor and the E column sensor determine that the person is ascending, it can be determined that the main column material III is ascending, and the F column sensor and the G column sensor are used. When it is determined that the person is ascending, it can be determined that the main column material IV is ascending. In addition, for example, when only the row A sensor is determined to be a person climbing tower, it is possible to determine that a person is climbing between the row A sensor and the main column material I.

  In addition, in the above, although the example applied to the steel tower 2 provided with the four main pillar materials 4 was shown, the main pillar material was distribute | arranged to each vertex of a substantially triangle by planar view (in three main pillar materials) In the case of application to a steel tower (configured), two sets of sensor arrays may be similarly installed and monitored for each of the three standing surfaces. Moreover, in the above-mentioned structure, although the example of the steel pipe steel tower was shown as the steel tower 2, it can employ | adopt similarly also in the steel tower using equal side mountain shaped steel. Furthermore, although the example of the steel tower 2 was shown as a standing body, the same structure is employable also with respect to another standing body.

  Furthermore, in the above-described configuration, the processing shown in FIG. 3 is performed for each sensor row. However, if it is simply detected that a person climbs the tower, all the sensor outputs in the lower stage are combined into one. In summary, all sensor outputs in the middle stage may be combined into one, all sensor outputs in the upper stage may be combined into one, and a detection signal may be sequentially detected from the bottom to determine that the person is in an uphill state.
